The Xampp Perl does not have the lib with the strict.pm;

Then it is broken by design and should be scrapped.

Seeing this, I tried to change the path in the Perl file to: #!c:/perl64/bin/perl.exe

As I told you back up there somewhere, Windows doesn't use the shebang line. (Though Apache under Windows might). That's why I though you might also have Cygwin installed.

If you use a Cygwin shell, that will emulate the *nix-style of shebang processing. Maybe the XAMPP Shell is something similar?

What output do you get from: set

What output do you see from: ftype | find "perl"?
